Theodore Modis (born August 11, 1943) is a strategic business analyst, futurist, physicist, and international consultant. He specializes in applying fundamental scientific concepts to predicting social phenomena. In particular he uses the logistic function or S-curve to forecast markets, product sales, primary-energy substitutions, the diffusion of technologies, and generally any process that grows in competition.[1][2] He is a vehement critic of the concept of the Technological Singularity.[3]

He currently lives in Lugano, Switzerland.



He went to Columbia University, New York, where he received a Masters in Electrical Engineering and a Ph.D. in High Energy Physics, (sponsor J. Steinberger). His secondary education was in Greece at Anatolia College in Thessaloniki, Greece.


Modis carried out research in particle physics at Brookhaven National Laboratories and CERN before moving to work at Digital Equipment Corporation for more than a decade as the head of a management science consultants group. He has on occasion taught at Columbia University, the University of Geneva, Webster University, the European business schools INSEAD and IMD, and was a professor at DUXX Graduate School of Business Leadership in Monterrey, Mexico between 1998-2001. He has been in the advisory board of the international journal Technological Forecasting & Social Change since 1991.[4] He is also the founder of Growth Dynamics,[5] a Swiss-based organization specializing in business strategy, strategic forecasting and management consulting.[6]


He has published about one hundred articles in scientific and in business journals, as well as nine books: Predictions, Conquering Uncertainty, An S-Shaped Trail to Wall Street (treating the New York Stock Exchange as an ecosystem), Predictions: 10 Years Later, Bestseller Driven, Natural Laws in the Service of the Decision Maker, Decision-Making for a New World, An S-shaped Adventure: "Predictions" 20 Years Later, and Fortune Favors the Bold: A Woman’s Odyssey through a Turbulent Century.[7] His books have appeared in a number of other languages; Predictions has been translated into German, Japanese, and Greek, and Conquering Uncertainty has been translated into Chinese Long Form, Chinese Short Form, Greek, and Dutch.

Praise for PredictionsEdit

  • "Interesting, well written, enjoyable, controversial, thought-provoking." - Simon van der Meer, Physicist, Nobel Prize 1984.[8]
  • "A lot of highly selective fun re-invoking much in my own past experiences." - George Wald, professor emeritus of biology at Harvard, Nobel Prize 1967.[8]
  • "You must read this book. It is the most delightful one on forecasting I have encountered in a very long time. Written for the enjoyment of both layperson and professional, it is fascinating and provocative." - Harold Linstone, Editor in Chief; Technological Forecasting & Social Change, 1992.[9]
  • "We have the technology now to forecast many social phenomena ... . I follow the work of Theodore Modis, who nicely sums up the case for utility and believability of predictions." - Kevin Kelly, Executive Editor of WIRED.[10]
  • "A fascinating technique for making forecasts." - THE FUTURIST.[11]
  • "... he (Modis) does cite the relationship of his 'overall' 56-year cycles and evidence on the associated clustering of technological innovations to prior work by Kondratieff and Schumpeter (in my opinion, Modis’ evidence on these topics is more extensive and compelling than that of either of these scholars.)" - Kenneth C. Land, SCIENCE.[12]
  • "Can a well-known mathematical equation be used to predict a wide range of human activity? Maybe." - Vernon Church, NEWSWEEK.[13]

iPhone/iPad ApplicationsEdit

He has created two applications for iPhone/iPad, The S_Curve and Biorhythm_Science. Together with Vasco Almeida they created applications that forecast stock prices like species by treating the stock market as an ecosystem: Stock Fcsts and 2Stock Fcsts[14] for the iPhone and Stocks' Futures and 2Stocks' Future[15] for the iPad.[16]
